Thermal performance

These thermal models demonstrate the superior insulation provided by the Thermal Heart™ barrier.

• The top illustration is a Thermal Heart™ frame with clear double glazing. The outside air temperature is 3°C but the inside frame temperature is now a warmer 15°C.
• The bottom illustration shows a clear double glazed window without a thermal break. The outside air temperature in this instance is 3°C while the temperature on the inside of the frame is 8°C.
